ZIF Connectors

DLD

DLD Drawer Product Introduction

Cannon has combined Zero Insertion

Force (ZIF) technology with remote

electrical engagement. The DLD Drawer

allows the movement of a drawer or panel to

effortlessly mate/unmate the connector halves. As

an example: electrical sub-systems can be easily

removed for service, interchangability, or

portability.

By specifying DLD Drawer interconnect systems,

your packaging design is simplified as the need for

expensive, complicated, and space-consuming

manual actuation mechanisms is eliminated. Tight

space requirements no longer restrict your use of

ZIF connectors.

The contacts in the DLD Drawer product line do not

touch each other while the connector halves are

mating. This unique ZIF technology, introduced in

the Cannon DL series in the early 1970’s, has

time-tested proven reliability and durability.

The DLD Drawer’s remote mating feature utilizes

the axial thrust of a cam to move and mate the

contacts. At the end of the cam travel, the cam

ramps on a flat surface thereby negating any

uncoupling forces.

This rack-and-panel connector is available with

crimp or square post contacts, allowing cable,

PCB, or flat-flex termination.
